Facing trouble with the codegen

[programVeins]

I just wanted to point out a few problems I faced while trying to generate swift code for OSlash's GraphQL schema. Tried running swift-graphql ${ENDPOINT} --authorization ${AUTH} but it resulted in the following error:

Error: valueNotFound(
    Swift.UnkeyedDecodingContainer,
    Swift.DecodingError.Context(
        codingPath: [
            CodingKeys(stringValue: "data", intValue: nil),
            CodingKeys(stringValue: "__schema", intValue: nil),
            CodingKeys(stringValue: "types", intValue: nil),
            _JSONKey(stringValue: "Index 10", intValue: 10),
            CodingKeys(stringValue: "interfaces", intValue: nil)
        ],
        debugDescription: "Cannot get unkeyed decoding container -- found null value instead.",
        underlyingError: nil
    )
)

I was wondering why this is being triggered because, swift-graphql uses decoder.container(keyedBy: CodingKeys.self) and the error says that an unkeyed decoding container was tried to parse. Does this mean the schema I am trying to parse has a few unkeyed nested containers? Will be cool if there's any known workaround for this! 🤔

@programVeins any chance that you paste here the result of calling the introspection query on your server? You can also send it to me privately.

I suspect the issue is that you have no interfaces and return null but the decoder expects an array.

Hey, I realized #66 can fix this issue, I did, in fact, tweak a local copy of the source code and it now works as expected! You were right about interfaces, they seem to have caused the issue.

Sounds like this was resolved and is no longer an issue, will close this issue to cleanup 👍
